@15g lui fttoznegf PATE-NT OFFICE HENRY Memoirs. or NEW Yoann. Y.,

, citizen of the United States of America, re- Y vsidingfat New Yorklcity, Bronx county,

State of New York, have invented certain new-and useful Improvements inWindow- Gruards, of which the ,followingis a full',

j cl'ear,and 'exact description.

This invention relates to improvements in window guards or devicesarrangedy for attachmentto a windo'wcas'ing toprevent a window cleanerVfrom* falling 'out of ,theL

A window. improved guard is arranged so that itV 'can be attached to awindowof any width vand also held in any position vertically 'of thewindow frame. My improved guardis arranged for attachment to a windowcasing without resorting to screws', bolts, etc. Y 'While my device isespecially arranged for'window cleaning purposes, it may also beused fas a guardto enable o nefto utilize the window sill forv flowers, etc.V

One of the advantagesof: my vimproved guard is that itis simplefan'deffective and cheaply manufactured, as it isdesigned to obviate thenecessity of machining. The frame which forms pa'r'tofthe device will bepreferably cast, a suitable clamping device being employed to enable itto be securelyV -aixed to a window, frame.v The clamping device, which Iemploy, is of` simple construction, durableand easily manipulated. f

Other features of my .invention will be hereinafter set forth.

I will now proceed to describe my inven ltion inkdetail, the novelfeatures of which I will finally claim, reference being had to theaccompanyingl drawing, wherein Figure 1 is a sectional plan view of awindow frame, having myimproved guard applied thereto;

Fig. 2 is an enlarged sectional view,the section'being taken on a line 22 in Fig. 1;

Fig. 3 is an enlarged sectional detail view, the section being taken ona line 3-3 in Fio. 2 Fig.7 4 is an enlarged vertical sectional view, thesection being taken on a line 4 4 in Fig. l;

Fig. 5 is a sectional view, taken on a line 5 5 in Fig. 4; and Y Fig. 6is an enlarged detail view, in side elevation, of one of the .members oftheV clamping mechanism. f

l, prises frame-members `and'8 which arearrangedfor applicationto a'window frame 9. In thisinstanee, lI have illustrated the frame members7 and'S as applied/to the guide kmembers 1Q forfthe window sash,v

whichl operate inthe channels 11, an illustration of said sash rbeingomitted, the channel 1.2 being for the other. window sash,y which isvalso not shown. VEach frame 7 and Sis provided withjaw members 13 and14` to receiveaguide .member'10. c. Each `frame is also vpreferablyprovided, with avthird i member 15 to also engage said guide Vmember 10Afor a purpose to be setk forth. Each frame and 8,is.also provided withypassages therethrough, indicated by f16, to receive rods4 or trusses.-17. p Each frame7 and 8 is further provided with a guide-wayflS to. y

slidably receivea hollowblock V19,engaged atoneend 'by links 20, theopposite end of yeaclrof said links being in lengagement with 'y iVtherods or trussesv17.A VThe blocks 19,`are moved longitudinally of theguide-ways 18 in one direction, bynuts 21-eng'aging bolts"vv80 22carried bythe said blocks.' and passing through the end'wall 23 oftheguide-ways.:

18'.y Thelinks .20, as welly as bolts 22 pass through the blocks 19,which are hollow, being provided with an opening 24 there# through. Theend wall 23 of each guide# way 18 is provided withy a recess or slot A25to enable the bolts 22 and links 20 to be connected to the blocks 19.before being applied to the frames. In other' words, after the bolts 22and links 20 are connected to blocks 19, thesaid blocks can be insertedinto the guide-ways by being slipped in'sidewise, as

i the bolts 22 will enter the slots 2,5l (see arrow i To attach thedevice toa window casing,

:the jaw members 13 and 14 of each yframe 7 26, Fig. 3).

and 8 will beapplied to the adjacentwindow guide member 10, rods 17having first been slipped through the openings .16, atthe outer end ofthe frames. The lrods 17 kmay be of any suitable material, such as woodor metal. j When the rods are passedk through the openings 16, they alsowill be passedL through the links 2O (see Fig. 2), said links Yand block19, together with the bolts 22,V having been previously applied to theframes 7 and 8. After frames 7 and 8 have been applied tothe guidemembers 10, they will be forced against the same and the rods 17 causedto be jammed against the frames 7 and 8, with! in the openings 16, bymeans of the'bolts 22,

which are caused to draw the blocks 19 in a direction away from the rods17, which action will tend to pull the links lin a direction to tightlybind the rods 17 and frames to gether. After the rods are jammed, theframes will be held against movement in a direction kthat Would causethem to becomen separated from the guide-members 10.

Under ordinary conditions, the frames 7 and 8 will rest upon the sillportion 27 of the Window frame, but may be supported in an elevatedposition relative'to the sill (see Fig..2), by means of a lockingmechanism,V

consisting of a cam 28 actuated by a lever 29 through themedium of ashaft 30, which carries the cam 28. 'The cam 28 will be sup-'ported-within a pocket 31 formed in the vthe iframes will be held.

third jaw-member 15 carried by each frame V7' and 8.V Y VAfter thedevice has been elevated to the s guard or fence, so to speak, againstwhich a V window cleaner can lean, or against which articles can beplaced.

The cam 328 Will be preferably provided j day of February,

with a blade 30n to dig into'the guide mem ber 10; hence I need notaltogether depend upon the pressure of the cam to hold the frames inplace.

Having described my invention, what I claim is 1. In a window guard, aframe having jaws to engage a window casing, said frame being providedwith an opening, a rod engaging said opening, said frame being furtherprovided with a guide way, a block slidable in said guideway, means toactuate said block, Aand a link carried by the block arranged to engagethe rod to force the rod against the wall of the opening engagedthereby.

2. In a window guard, a frame, means carried thereby, to engage a Windowcasing, a rod releasably supported by the frame, a link engaging saidrod, and. means carried by the frame to actuate the link to draw the rodfirmly against said frame.

3. A window guard assembly, consisting of a pair of frame membersarranged to releasably engage a window casing, rods releasably engagingthe frames, binding means engaging the rods and located adjacent theframes, but not connected thereto, and means carried by each frame toactuate the adjacentbinding means to lock the frames and rods firmlytogether.
